A proportional relationship is also known as a direct variation

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In a proportional relationship

If the variable x increases -------> the variable y increases

If the variable x decreases -------> the variable y decreases

Answer:

D. f(x) = 4x - 3

Step-by-step explanation:

Use two pairs of points to work out the equation:

(1, 1) and (2, 5)

Find the slope:

m = (5 - 1) / (2 - 1) = 4/1 = 4

Find the y-intercept:

1 = 4*1 + b
b = 1 - 4
b = - 3

The line is:

f(x) = 4x - 3

Correct choice is D

How to solve for area of triangle where A=67 degrees, b=11yd, and c=24yd

skad [1K]

Use the formula of an area of a tringle:

$A=\dfrac{1}{2}bc\sin A$

We have b = 11 yd, c = 24 yd and m∠A = 67°

$A=\dfrac{1}{2}(11)(24)\sin67^o$

$\sin67^o\approx0.9205\\\A=(11)(12)(0.9205)=121.506\ yd^2$

Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certific

Ulleksa [173]

Answer:

Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.
